Maybe I’ll just get the .38 spl I’ve got my eye on then. I thought maybe it would be a good jack of trades but from you all and from what I read it’s ok with 410 loads but not as good as a real 410 and it’s ok with 45 but not as good as a real 45.
My experience with the S&W Governor, Bond Arms Derringer, Henry Lever action, Chiappa Double Badger, Rossi Tuffy, and Rev Eternal 410 all chambered in .410 is that while the .410 shotshell is loaded in an insane amount of offerings, each platform really only performs well with a select number of them.
The Taurus Judge for instance is terrible with .410 slugs (barrel length too short to reach the velocity that makes .410 slugs perform well) and birdshot (rifling makes the pattern terrible) but good with buck shot designed for it. So while yes the Judge has the option to shoot an insane variety of loads it is only excellent with two of them as far as I can tell. The Federal Premium Buckshot (good luck finding that) and the Hornady Critical Defense.
Honestly for what you are describing you might be well serviced by a Rossi Tuffy single shot .410
It is cheap (Easily under $200) , fairly compact in size compared to standard shotguns (OAL of 31 inches), stores 8 rounds in the stock, ejects spent shells smoothly, a little under 3 lbs in weight (get a butt pad), flings .410 slugs at full speed so they hit like .357s, and is smooth bore so you could also shoot shot out of it if snakes are an issue too.

From your initial post just about the only reason I wouldn't recommend this firearm for you is that it might be too big for the cab.However the OAL of the 6.5 inch Judge is 12.5 inches, so you are already looking at a large handgun.
